Power Supply Switching Buffer PULSAR DING2 DING2-12V2A 13.8V 2A

PULSAR DING2-12V2A is a compact switching buffer power supply that provides a stabilized output of 13.8 V DC with a maximum current of 2 A. Intended for continuous operation, the unit offers voltage regulation and short-term buffering to support low-power security, communication and automation devices. Its small footprint and mounting options make it suitable for installations where a reliable 13.8 V source and temporary backup are required.

Advantages

The switching topology delivers stable voltage with good efficiency and reduced heat generation compared to linear designs. The device is designed for continuous duty, offering steady output under nominal load and protection against common electrical faults. Compact dimensions and multiple mounting options allow easy integration into wall- or rack-mounted systems, while the regulated 13.8 V output ensures compatibility with a wide range of CCTV, access control and low-power telecommunication equipment.

Suitable for

• Small IP or analog CCTV cameras and camera modules
• Access control panels and card readers
• Low-power alarm panels and sensors
• Communication devices and routers requiring 13.8 V supply
• Automation modules and low-current peripherals needing short-term buffering

Key specifications

• Output voltage: stabilized nominal 13.8 V DC
• Maximum output current: 2 A
• Operating mode: continuous (24/7) with buffering capability
• Type: switching (high-efficiency switching regulator)
• Form factor: compact unit suitable for wall or rack mounting
• Intended use: backup/regulated supply for low-power security and communication equipment

How to use

Install the power supply in a dry, ventilated location appropriate for wall or rack mounting and connect the AC input according to local electrical regulations. Connect the 13.8 V DC output to the device(s) requiring power, observing correct polarity. If the load approaches the maximum current, verify temperature and mounting clearance to ensure adequate cooling. For backup or buffering applications, integrate the unit with batteries or the system's existing backup arrangement according to the manufacturer's wiring recommendations.

Usage recommendations

Use the power supply within its rated current and voltage limits and follow local wiring codes. Allow clearance for ventilation, avoid installation near heat sources, and perform periodic inspection of connections. When used as a buffer in security or communication systems, verify compatibility with connected equipment and plan for appropriate battery capacity if extended backup is required.
